We numerically investigate the erosion potential of a cavitating liquid jet by means of highresolution finite volume simulations. As thermodynamic model, we employ a barotropic equilibrium cavitation approach, embedded into a homogeneous mixture model. To resolve the effects of collapsing vapor structures and to estimate the erosion potential, full compressibility is considered.Two different operating points featuring different cavitation intensities are investigated and their erosion potential is estimated and compared. Different methods are used for this purpose, including collapse detection (Mihatsch et al., 2015), maximum pressure distribution on the wall, and a new method of generating numerical pit equivalents. The data of numerical pit equivalents is analyzed in detail and compared with experimental data from the literature. Furthermore, a comprehensive grid study for both operating points is presented.

“…In this case, the existing models play important roles for solving problems. There are many authors (Doner et al [1], Kaufhold et al [2], Wang et al [3], Nayyeri et al [4]) who have worked on modelling and simulation on different metallic materials. This paper is based on the numerical simulation of the experimental work presented by Singh et al [5] in which obtained material parameters of C-S model [6] and J-C model [7] are used to simulate the problem in ANSYS.…”

The objective of the paper is to simulate the behaviours of mild steel at different strain rates (1-1500s -1 ) under tension and compression by using finite element analysis code in ANSYS. Numerical simulation are done using Cowper-Symonds (C-S) and Johnson-Cook (J-C) material models to represent the flow stresses of mild steel. The simulated results have good agreement with the predicted results of the above material models.
